Activity:

Place the solar panel face down on any surface. Do not connect the USB port on the Solar Battery. Run the program and observe the number of LEDs that light up. Slowly move the solar panel towards the sun and observe the change in the LEDs. Rotate the solar panel right, left, up and down and find the orientation where the maximum number of LEDs are on. That is the best panel orientation where the maximum energy from the sun is converted to electricity.

Conclusion

Learning to control solar power with computers like the micro:bit opens up a new, plentiful and non-polluting energy source.
